Propped fracture conductivity of influencing factors
A propped fracture Proppant flow capacity is the physical properties and the conditions in which the comprehensive reflection of cracks, it is the proppant selection and optimization of the design of one of the most critical parameters. Propped fracture conductivity affect more factors, including: the propped fracture withstand the force, the physical properties of the proppant, the proppant in the fracture and proppant concentration laid on rock embedding, time and fracturing pressure liquid on the propped fracture injuries and many other factors.
2 stress and pore pressure support band formed after  fracturing proppant  in the fracture closure pressure to bear, it is the formation in situ stress that the minimum principal stress and pore pressure difference, usually equivalent fracture pressure and bottomhole pressure difference between the different types even though the proppant, but their conductivity capabilities are closed with the pressure increases.
3, the concentration of proppant laid concentration of  Proppant  s laid on the wall of the support unit dose cracks, commonly expressed kg/m2. Fracture conductivity  frac proppant  with laid concentration increased, multi laid proppant can not only reduce the degree of fragmentation, but also increase the crack width.
4, the proppant crushing and embedded in the support belt when the crack is closed when the proppant particles will be embedded in the wall Fracture or rock crushing rock, both of which affect the effective fracture width and fracture permeability, thus affecting fracture conductivity decreases. When hard rock, crushed the main influence; soft formations, the main are embedded.
